This paper is to indicate the principles and design methods of USB application software under Windows and WDM driver for USB device.

Objective: To achieve intelligent access to normal training or individual soldier signs information during the war, establish individual soldier health intelligent interactive regulation and health system platform of IOT, realized digitalization, information management mode. Methods: Using the communication network, intelligent call, vital signs monitoring technology, to design intelligent signs monitoring system. Results:This system is mainly for the automatic sense of individual signs in the training or war, to understand the individual activity, get the sign data, which can send information through a call or intelligent system, based on the identification and location, medical personnel to care and treatment in the shortest time, construction of intelligent information. Conclusion: Through the use of intelligent detection system to Individual life signs in training or in wartime, the system can always grasp of individual soldier signs, and realizing a complete coverage of all of the intelligent health monitoring system, to provide effective guarantee for wartime workers health.

Objective: The mobile medical collaborative service platform can realize mobile nursing informatization, which will bring new changes to the nursing work, and work flow is optimized. The construction of mobile nursing system is the trend of development in informatization, in order to better service to patients, realize full nursing work informatization. Methods: Based on wireless dynamic environment, and three subsystems including nursing collaboration portal, intelligent mobile terminal application system, the message engine service system, it adopts hierarchical architecture design, based on SOA structure mode, whose modules are loosely coupled, and platform core includes: the message engine subsystem, the medical task analysis engine subsystem, WEB middleware subsystem and the client subsystem,in order to realize the service management of mobile medical collaboration. Results: According to the actual situation of nursing work in hospitals, construction of mobile nursing system by the stage of application, to meet the core work of nursing, and then realize the basic nursing work, the construction of digital implementation of nursing information, to realize the informatization construction of digital care. Conclusion: Application of the system to achieve the whole informatization of the nursing management, through access to health services, cloud services center, to share resources, to achieve full coverage of all aspects of smart care management for people's health to provide effective protection.

OBJECTIVE:To prepare rufloxacin eye drops METHODS:The content of rufloxacin was determined with HPLC method The therapeutic effect of the eye drops was observed in 150 out-patients with severe ocular infections RESULTS:Determined by HPLC method,the average recovery of rufloxacin was 100 12%(RSD=1 18%) After treatment,130 patients recovered,16 improved and had no efficiency with a total effective rate of 97 33% CONCLUSION:The eye drops have definite therapeutic effect The HPLC method is simple,rapid and accurate in determination of the content and no special reagent is needed

Objective: To design device to measure D/T index which is used for evaluation of arteriosclerosis. Methods:By calculating the detected date of blood pressure values, pulse pressure, pulse rate, pulse patterns and SpO2 on the extremities, we get a set of analytical data in the system in order to analyze the arteriosclerosis situations. Results: The device use the ECG signal as it based and modulated signal, the computer process the date of blood pressure and SpO2, then output the result by the display and printing systems. Conclusion:The device provides an effective noninvasive detection means for extremity vascular.

Mobile X-ray system is a very important equipment in hospital,but it's difficult to protect the user from the exposure of the X-ray while the equipment is in use.This paper introduces a circuit that is able to control the exposure by remote controller and it can solve the problem of the protection better.The efficiency is proved to be good by experiments.

Objective　To obtain mammalian cell expression vector of human CD154 gene. Methods　A 820 bp cDNA fragment was amplified by RT-PCR method from total RNA of human peripheral blood mononuclear cell（PBMC） activated with 10 ng／mL PMA and 1 μg／mL PHA for 8 hours. The fragment was cloned into pcDNA3.1（＋） plasmids.The cloned insert was identified by double digestion of the recombinant plasmid with restriction enzymes BamH Ⅰ and EcoR Ⅰ and sequenced by Sangers-dideory-mediated chain termination. Results　This cDNA fragment included 820 bp entire coding region and a part of the 3 non-coding region. The recombinant mammalian cell expression vector of pcDNA3.1（＋）／hCD154 was constructed， the sequence of the insert was identical to the published sequence encoding human CD154 antigen. Conclusion　The recombinant mammalian cell expression vector of pcDNA3.1（＋）／hCD154 was successfully constructed.

Nervous function stimulating system is a stimulus delivery and experimental control software system for neuroscience.The purpose of this paper is to indicate the principle and design method of nervous function stimulating system based on USB Bus.It was designed for behavioral and physiological experiments using FMRI,ERP,MEG,reaction times,and single neuron recording.
